SEATTLE, WA, — LifeSpan BioSciences, Inc.(LSBio), a leading provider of antibodies for researchers worldwide, has increased the number of validated IHC-plusTM antibodiesavailable in its catalog to more than 10,000. With this increase, LSBiois well on its way to its goal of building the world’s largest catalog of 20,000 well characterized, IHC-validated reagent antibodies. Overall, LSBiohas a catalog of more than 129,000 antibodies validated for use in many types of assays.

IHC-plusTM antibodies, LSBio’sflagship product line, consists of antibodies that LSBiohas validated for use in IHC, drawing on its 17-year track record in designing, manufacturing and using antibodies for immunohistochemistry (IHC). These antibodies have been extensively tested against formalin-fixed paraffin-embedded (FFPE) human tissues. Each antibody has been characterized at four different concentrations against 22 normal human tissues, plus additional controls. These antibodies have been identified as the best reagents for use in FFPE-IHC.

Immunohistochemistry is widely used to visualize proteins (and other antigens) in tissues, and can detect any protein encoded by the 21,000 genes in the human genome. In addition, IHC can detect functionally important protein modifications (such as phosphorylation). To visualize an antibody-antigen interaction with IHC, tissue specimens are fixed in formalin and embedded in wax, and thin sections are placed on microscope slides. After incubation with an antibody, the bound antibody is stained with a dye, and the slides are examined under a microscope by a pathologist to detect specific molecular markers. All of LSBio’sIHC-plusTM antibodies are documented with high resolution images of stained tissues, which are of great value to researchers in evaluating antibody specificity and their suitability for their own studies.

“Our 17-year history in delivering IHC services and validating antibodies makes LSBiouniquely qualified to meet the need for high-quality, IHC-validated antibodies to thousands of new protein targets,” said Glenna Burmer, M.D., Ph.D., chief scientific officer and executive vice president. “LifeSpanis rapidly becoming the market leader for these important antibody reagents.”

LSBiohas grown its antibody business exponentially over the past five years, and thousands of researchers in more than 50 countries across Europe, Asia and North America now rely on LSBioBioSciencesfor their antibodies.

“With our rapidly expanding product line, our reagent antibody revenues have increased rapidly over the past few years and we expect them to continue to do so,” said LifeSpan’sCEO, Joe Brown, Ph.D. “In 2013, we are continuing to aggressively expand our antibody catalog of IHC-plusTM antibodies to create value for our customers and strategic partners, and to strengthen our business for the future.”
